紫草是一种优质的饲料作物。1977年春,我们从京山县种畜场引进紫草两蔸,从3月8日到10月19日连续多次进行了切根繁殖、分蔸繁殖和茎秆扦插繁殖的观察试验。截至10月底止已繁殖到4,000多株,定植大田2.8亩。试验观察表明:紫草繁殖系数高,适宜繁殖的季节长,从3月上旬到10月中旬
Lithospermum is a good feed crop. In the spring of 1977, we introduced Lithospermum tuberosum from the breeding farm in Jingshan County. From March 8 to October 19, we conducted continuous observation and experiment of cutting, breeding and stalk cutting reproduction. As of the end of October, more than 4,000 plants have been bred and 2.8 m of fields have been planted. Experimental observations show that: Lithospermum reproductive coefficient is high, suitable for the breeding season, from early March to mid-October
